There are many (like me) who just don't care until it hits them.

But more so it is a kind of laziness, an oblivion, like a crab in a 
cooking pan, slowly turning up the heat, but you don't notice it.

I think our society at large has many such things going on. We rarely 
have backup plans and most of our infrastructure is not redundant at 
all. I would not say our society is built for resilience but what 
happens if the lights would go out for 30 days straight? No electricity 
anywhere?

I think that is the same kinda thing. We just hope it will go on forever 
until it hits ;-).
